In formula: Δ Q is flow change rate, Q
0flowmeter reading during for test 0h, Q
tfor flowmeter reading after test 168h.
Δ Q value is less, and hydraulic oil is described, and more viscosity performance is more stable.
embodiment 3:
The principle of test is: at hydraulic pump 4, in the time dispatching from the factory, the discharge capacity parameter of its hydraulic pump 4 is fixed, different output pressures, and its discharge capacity is also different.In the time that hydraulic system output pressure parameter, hydraulic pump 4 discharge capacities and hydraulic pump 4 power inputs are fixing, the internal leakage of hydraulic pump 4 is less, and delivery rate is larger, i.e. hydraulic cylinder to-and-fro movement one-period time used is less.In use procedure, the larger system internal leakage of viscosity is less, but the energy loss that the interior friction of hydraulic oil causes is larger.By hydraulic oil stability meter, finding equilibrium point aspect internal leakage and energy loss two, select the hydraulic oil of most suitable viscosity grade.
The step of test is: open each equipment by thermostatical oil bath 11, heating fluid force feed sample to 75 DEG C constant temperature.Open hydraulic pump 4, equipment entry into service, setting revolution speed power input is 6 kilowatts, in system, hydraulic fluid pressure is 25Mpa.Measure while using different viscosities rank hydraulic oil the uninterrupted of hydraulic system.Hydraulic oil viscosity rank when flow is maximum is the hydraulic oil of the viscosity grade of the most applicable equipment use.
Finally it should be noted that: obviously, above-described embodiment is only used to clearly illustrate the utility model example, and not to the restriction of implementing.For the those of ordinary skill in described field, can also make other changes in different forms on the basis of the above description for example change of the shape of spring clip 9, temperature control and the insulation of heating system 8 and the change of heat form etc.Here without also cannot be to all embodiment with exhaustive.And the apparent variation of being amplified out thus or variation are still among protection domain of the present utility model.
